Flame-retardant sound-absorbing board

The physical and mechanical properties, appearance and post-processing properties of most flame-retardant polyester (including filament and staple fiber) are similar to those of ordinary polyester. Only a few fibers (such as wistel Fr) have a slightly lower strength than ordinary polyester, but do not affect textile processing. Because the structure of flame retardant fiber is loose, dye molecules are easy to enter, so the dyeing speed is faster than ordinary polyester, and can be dyed with disperse dyes or cationic dyes.
